IMPROVEMENT IN RAILWAY-SWITCH STAND.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom it may concer-n:

Be it known that we, R. L. MOGOWAX und WALTER FLETCHER., of Alliance, inthe Stute ot' Ohio, have in- `vented n new amd useful Improvement inSwitch-Stands p and we do hereby dechire thai-t the following is e full,

` tion zuid operation..

Similar letters, in the drawings, refer to like parts. This inventionconsists in the novel 'construction zuid combination of en elasticswitch-lever with a. notched slot in the switch-stand, zuid e slidingkey, connected' with the lever, whereby the switch is renderedselflocking, and. is prevented from displacement by any accidentellateral pressure.

In the drawings, Arepresents switch-stand, of oro dinery construction,longitudinally of which, in thc top,

is a. slot, a, through which passes the switch-lever c,

mede elastic. y

Three or more recesses, w', open out of one side of the slot a, intoeither of which recesses the lever c' slips, as, in passing along the.slot (t, it comes pposite such recess. v

Ixfthe drawings, the lever is shown its occupying the middle recess,When in this position, it is-obvious thettlie lever is securely lockedagainst any lateral pressure, and this, too, without then-id of holt,bi1-r, or-

pin, or any other device which may be displaced or lost.

To prevent the lever from displacement under trzuisl verse strain, weattach to it the sliding` key l), which, when the lever slips into oneof the-recesses, falls; olf

its own accord, into the slot in front' of the lever, eindsecurelyitstens it.

Then the key is raised out of the slot-,the lev'er may be sprmig out ofits recess, luid be moved back' or foith in the slot.

Having thus described our invention,"

Y That we clziim as new, und wish to secure by Letters The lever c, incombination with the sliding keyl b, slot a, :nid-recesses a',substantially es described.

In testimony that we claim the foregoing, We have hereunto set oiuhands, this 8th day of September,
